WebExcited state intramolecular proton transfer (ESIPT) is a process in which photoexcited molecules relax their energy through tautomerization by transfer of protons.Some kinds of molecules could have different minimum-energy tautomers in different electronic states, and if the molecular structure of minimum-energy tautomer in the excited state is proton … WebSep 26, 2024 · It follows from Equation ( [e13.128]) that the modulus squared of the dipole moment for the 2P → 1S transition takes the same value d2 = 215 310 (ea0)2 for m = 0, 1, or − 1. Clearly, the transition rate is independent of the quantum number m. It turns out that this is a general result. Now, the energy of the eigenstate of the hydrogen atom ...
